SiC MOSFET vs SiC/Si Cascode short circuit robustness benchmark
2019
Abstract Nowadays, MOSFET SiC semiconductors short circuit capability is a key issue. SiC/Si Cascodes are compound semiconductors that, in some aspects, show a similar MOSFET behaviour. No interlayer dielectric insulation suggests, in theory, Cascode JFETs as more robust devices. The purpose of this paper is to compare the drift and degradation of two commercial devices static parameters by exposing them to different levels of repetitive 1.5 μs short-circuit campaigns at 85% of its breakdown voltage. Short-circuit time has been set experimentally, and longer times result in catastrophic failure of MOSFET devices due to over self-heating. For this purpose, pre- and post-test short circuit ch…
A single preoperative pain neuroscience education: Is it an effective strategy for patients with carpal tunnel syndrome?
2019
Patients undergoing carpal tunnel release surgery may continue to experience pain despite the intervention. This symptom may be modulated by psychosocial factors including depression, catastrophic thinking, and kinesiophobia. Pain neuroscience education (PNE) has been found to be effective when combined with therapeutic exercise in patients with chronic pain, but this strategy has not been evaluated in patients with persistent hand pain. The findings of this study indicate that a single preoperative PNE session in combination with therapeutic exercise does not provide added benefits in comparison to standard preoperative care plus therapeutic exercise. Future studies should evaluate if pati…
Does the educational level of women influence hand grip and pinch strength in carpal tunnel syndrome?
2020
Abstract Background Grip and pinch strength are relevant functional variables for various activities of daily life and are related to the quality of life of patients with carpal tunnel syndrome (CTS). Objective The main aim was to analyze the relationship between grip and pinch strength and the educational level in women with CTS. Study design Cross-sectional study. Methods Thirty-one female patients with CTS awaiting surgery were assigned to the low education group if they only had primary education level (completed or not) and the high education group for those having higher education level. The assessments included: grip strength, pinch strength, Visual Analogue Scale, Quick DASH Questio…
A putative antiviral role of plant cytidine deaminases
2014
[Background]: A mechanism of innate antiviral immunity operating against viruses infecting mammalian cells has been described during the last decade. Host cytidine deaminases (e.g., APOBEC3 proteins) edit viral genomes, giving rise to hypermutated nonfunctional viruses; consequently, viral fitness is reduced through lethal mutagenesis. By contrast, sub-lethal hypermutagenesis may contribute to virus evolvability by increasing population diversity. To prevent genome editing, some viruses have evolved proteins that mediate APOBEC3 degradation. The model plant Arabidopsis thaliana genome encodes nine cytidine deaminases ( AtCDAs), raising the question of whether deamination is an antiviral mec…
Aplicación de modelos digitales a la determinación del valor de vistas al mar en las áreas turísticas de litoral
2019
El uso masivo de datos geográficos requiere de información cartográfica. Los modelos digitales derivados del procesado de datos LIDAR (Light Detection and Ranging) se plantean como fuentes de información, entre otros campos, en el análisis del paisaje urbano. Así, su aplicación permite la valoración de las líneas de horizonte de un observador situado en un entorno urbano. Esta es una cuestión especialmente relevante en las áreas turísticas de litoral, donde, por ejemplo, las tarifas son distintas entre habitaciones de un hotel con o sin vistas al mar. El objetivo de este trabajo es analizar las debilidades de los métodos de captura automatizada de datos para la valoración de las líneas de h…
Terremotos, memoria y miedo en la Valencia de la Edad Moderna
2012
El carácter destructivo de los terremotos ha provocado siempre un miedo apocalíptico en las gentes. Este artículo estudia los movimientos sísmicos en tierras valencianas durante los siglos XVI-XVIII, sus consecuencias y el modo con el que la iglesia mantenía vivo el “miedo” a un Dios implacable con los pecados de las gentes y causa primera de todo desastre natural. The destructive nature of earthquakes has always caused apocalyptic fear in the people. This article studies earthquakes in Valencian lands during the XVI-XVIII centuries, its consequences and the way in which the church kept alive the “fear” of an implacable God with the sins of the people and the first cause of all natural disa…
Pain Neurophysiology Education and Therapeutic Exercise for Patients With Chronic Low Back Pain: A Single-Blind Randomized Controlled Trial.
2018
Abstract: Objective To assess the effect of a pain neurophysiology education (PNE) program plus therapeutic exercise (TE) for patients with chronic low back pain (CLBP). Design Single-blind randomized controlled trial. Setting Private clinic and university. Participants Patients with CLBP for ≥6 months (N=56). Interventions Participants were randomized to receive either a TE program consisting of motor control, stretching, and aerobic exercises (n=28) or the same TE program in addition to a PNE program (n=28), conducted in two 30- to 50-minute sessions in groups of 4 to 6 participants. Main Outcomes Measures The primary outcome was pain intensity rated on the numerical pain rating scale whi…
Determinants of health-related quality of life in patients with persistent somatoform pain disorder
2003
Background. Health-related quality of life (HRQOL) has been investigated widely in patients with chronic pain, but no study has focused particularly on the situation of patients with persistent somatoform pain disorder. Aims. To survey the impairments of patients with somatoform pain disorder (ICD-10: F45.4) and to predict pain-related impairments and HRQOL on the basis of coping styles. Method. A consecutively recruited sample of 100 patients (65% female) was examined in a cross-sectional study. Questionnaires were administered to assess pain intensity (visual analogue scale), pain-related disabilities (Pain Disability Index), quality of life (Short-Form Health Survey-36), and ways of copi…
Dental trait anxiety and pain sensitivity as predictors of expected and experienced pain in stressful dental procedures.
2004
A prevailing hypothesis suggests that exaggerated pain expectations in dentally anxious and pain-sensitive patients might usually be disconfirmed by a lower level of pain experienced during treatment. The present study was conducted to investigate whether this contention also holds during stressful dental procedures. Patients reporting high and low levels of dental fear and of pain sensitivity were compared in their expected and experienced pain and in the concordance between the two measures. Participants were 97 patients undergoing extraction and root canal treatment. The measuring instruments used were the Dental Anxiety Scale (DAS), the Pain Sensitivity Index (PSI), affective and sensor…
How much Is needed? Comparison of the effectiveness of different pain education dosages in patients with fibromyalgia
